Imidacloprid is a systemic insecticide with translaminar activity and with contact and stomach action by binding to postsynaptic nicotinic receptors in the insect central nervous system. Easily taken up by the plant and further distributed acropetally, with good root-systemic action. Used to control sucking insects, including rice-, leaf- and planthoppers, aphids, thrips and whiteflies. Also effective against soil insects, termites and some species of biting insects, such as rice water weevil and Colorado beetle. Has no effect on nematodes and spider mites. Used as a seed dressing, as soil treatment and as foliar treatment in different crops. Also used to control fleas on dogs and cats.
